If you’re a lover of sea days and making the most of a luxury cruise ship, you may be interested in the 10-night transatlantic cruise on Crystal Serenity, departing on November 12. The itinerary features a mere two port calls, one in the Azores and the other in the Caribbean. In between, you’ll have seven sea days (five of which are consecutive) to participate in ballroom dance workshops, learn to play piano or speak Spanish, practice your golf or bridge game, and listen to expert lecturers on topics such as baseball history, astronomy and voice acting. Fares start at $3,430 per person for an outside cabin.
